You need to know the difference between RMG industry and dyeing. Bangladesh is into RMG, where the actual yarn is mostly brought in from china, korea, and INDIA, so the pollution is happening in your back yard, all we do is give our poor work.
India is trying to build its economy from a top down approach, so thats why you see a lot of service tech firms and BPOs. This approach is good for a select few people, who earn a lot relative to the general population, and as long as they spend their earning in india then the wealth can filter down. How ever if they send their money abroad, import consumer goods, gold, invest overseas or take holidays, it does not perculate down.
Bangladesh has taken the opposite approach, we are looking bottom up approach, concentrating on using low cost labour, giving the poor, mainly women work and increasing their spending power. This approach means the amount earned stays mainly within bangladesh, not in swiss banks or invested abroad giving jobs to others, we dont want huge disparity in wealth, few billionaires and the rest.
These are 2 different approaches, one top down the other bottom up. Though we are one of the largest RMG exporters, we are now starting to diversify the economy, we are actively looking to build our light industries and setting EPZs to encourage industrialisation and the in a few years we will target the information sector.
